Martin Scorsese reunites with Robert De Niro in "The Irishman," a 3½-hour-long mob drama the acclaimed director said he chose to do with his frequent collaborator to build on their past work together rather than replicate it.

Set over several decades, "The Irishman" looks at a Pennsylvania organized crime family with Oscar winners De Niro, Al Pacino and Joe Pesci in the main roles.

The Netflix movie, which closes the BFI London Film Festival on Sunday, uses digital de-ageing technology to show the characters in their 30s and 40s. De Niro, Pesci and Pacino are all in their 70s.
